-LRB- CNN -RRB- -- `` I do n't think the euro should exist , '' said Saxo Bank co-CEO Lars Seier Christensen to CNN 's Richard Quest , in terms that could hardly be less fractious to supporters of the 17-nation single currency bloc .

`` It 's quite clear that what lacks here is fiscal union but it 's also very clear that the populations of Europe are not supportive of that goal . ''

The eurozone will also pull itself apart as competitiveness will continue `` to develop in different directions , '' said the head of the online Danish investment bank . He added that the people of the eurozone -- in particular , Germany as the monetary zone 's prime pillar -- will not make sacrifices for `` the weaker part of the eurozone '' -- Greece and other southern European countries .

Christensen 's controversial comments stand in stark contrast to what eurozone supporters have said -- advocating for austerity to keep the union together .

Germany , Europe 's largest economy , fears that a Greek exit from the eurozone could lead to a domino effect in which other massively-indebted countries -- Ireland , Portugal , Spain and Italy -- may pull out from the common currency , leading to the breakup of the eurozone .

In December 2012 , German Chancellor Angela Merkel won more support for bailout funds for Greece . In July , Mario Draghi , the president of the European Central Bank promised to do `` whatever it takes to preserve the euro '' which set off rallies for Greek , Spanish and Italian bonds .

Still , Saxo Bank 's Christensen believes the euro will disappear at some point in the future -- and despite hitting 13-month highs -- because he believes overall support does not exist .

`` I 'm not saying it 's a bad thing that support is not there , '' said Christensen , `` because the ability to adjust your currency is an important equilibrium between different economies and different developments . When that 's gone you 're left with a completely different set of problems . ''

The bank CEO declined to give a timeline but said it `` depends how long the Germans hold out ... how long the German population is willing to buy into supporting '' fiscal union .

`` I can tell you the problem is going to get greater rather than smaller ... I fear that the markets will take the thing apart eventually . ''
